| 中文摘要: |
| 以副子梁19.7万m3山体变形体治理工程为背景,通过现场调查、地质勘探、变形观测等手段,查明了变形体地形地貌、工程地质和水文地质条件。结合变形体的形变特征和破坏特征,分析了影响变形体稳定的主要因素。采用简化Bishop法,计算出剪出口的范围,确定最危险滑动面,建立了变形体稳定分析的模型,计算出自然状态、强降雨状态、地震状态3种工况下的安全系数,并进一步评价各变形体的稳定性。依据分析结果,进行处治方案的比选,针对各变形体采用经济合理的处治方案。最终处治方案的实施排除了可能的地质灾害隐患,同时为类似工程的理论分析及处治方案提供了参考实例。 |
| 英文摘要: |
| Based on treatment engineering of Fuziliang deformation mass, the topography, engineering geology and hydrological geology are investigated. Meanwhile, the failure characteristics, influenced factor and instability mechanism are analyzed. By using the simplified Bishop method, the range of shear outlet is calculated, and the most dangerous slip surface is determined, and the analytical model for the stability of deformation mass is established, and the safety factor of natural condition, heavy rainfall condition and earthquake condition is calculated, and the stability of deformation mass is further evaluated. At last, by Comparisons of treatment schemes, then economical and reasonable treatment scheme is adopted for each deformation mass. The implementation of the treatment scheme eliminates potential geological hazards, and an example for theoretical analysis and treatment scheme of similar projects is provided. |
